The dynamics and time scale of ongoing genomic erosion in symbiotic bacteria.

Science (New York, N.Y.) - 16 Jan 2009

Moran Nancy A, McLaughlin Heather J, Sorek Rotem

Abstract excerpt

Among cellular organisms, symbiotic bacteria provide the extreme examples of genome degradation and reduction. However, only isolated snapshots of eroding symbiont genomes have previously been available. We documented the dynamics of symbiont genome evolution by sequencing seven strains of Buchnera aphidicola from pea aphid hosts. We estimated a spontaneous mutation rate of at least 4 x 10(-9) substitutions per...
